ARKLOW MARSH against its type
Built in 2010, it is 3 years newer than the median general cargo ship on this register, which was built in 2007 (2,852 vessels with a known build year). At 9,758 gross tonnage it is larger than 65% of the other 2,665 general cargo ships with a recorded tonnage. It is one of 16 general cargo ships here under the Ireland flag, 0.5% of the 3,081 on the register. The same builder is recorded for 1 other vessel here, also a general cargo ship. The returns for 2018–2025 all give Arklow as port of registry.
Its 6,591 t of CO₂ for 2025 is 2.3 times the median of 2,820 t among the 2,469 general cargo ships on this register that reported for 2025. Per nautical mile it emitted 189.5 kg CO₂, 1.6 times the type median of 122.2 kg. It logged 3,087 hours at sea against a median of 3,044 hours for its type that year. 7.5% of its 2025 emissions were at berth; the median for general cargo ships was 4.3%. Across 7 years with reported emissions, the highest was 2018 (7,842 t) and the lowest 2024 (5,426 t). Its efficiency percentile within the type went from 39 in 2018 to 25 in 2025 (lower is more efficient). The one sister ship listed below with a 2025 return reported a lower CO₂ per nautical mile.

Efficiency against its own type2025
Position 119 of 479 qualifying general cargo ships by EEOI, at the 25th percentile. The dashed line is the type median, 29.4; this vessel reported 22.4.
EEOI divides emissions by transport work, which for this vessel and year was 294,379,634 tonne-miles over 34,774 nautical miles.
Reported CO₂ by year
Reported CO₂ in 2025 was 15.9% lower than in 2018, for EU/EEA voyages only. No return is recorded for 2023, so the series has gaps.
From 2024 to 2025, emissions rose 21.5% while distance sailed rose 30.6%and CO₂ per nautical mile fell 7.0%.That points mainly to how much the vessel sailed, rather than the other.
